Drawing functions, parametric or polar curves, choosing color, thickness and zoom.

Animating curves (translation, rotation, zoom, distortion) with persistence and colors gradient.

- Calculations by selection and move (a variant of the drag and drop adapted to touch use for tablets and smartphones) :
you select an expression then you put the cursor where you want and ask for a "Move (Calculation)".
EpsilonWriter proposes transformations when the situation allows them. The gestures are transformed to mathematical operations:
- numerical calculations, expand and simplify,
- factoring, simplification,
- adding to the 2 members (substraction, multiplication, division), substitution.

- Calculations on selection : you select an expression the you ask for a calculation. EpsilonWriter proposes an expression then you ask for a calculation. EpsilonWriter proposes calculations when the situation allows them :
- Exact or approximate numerical calculations, expand and simplify,
- Second and third degree equations solving schemes,
- Transform some logical conditions to a domain or a set of solutions,
- Limit calculation, derivative calculation,
- Table of signs, Table of variations,
- Formula generation,
- Complex numbers calculations.

- Questions with a single or several choices
- Calculations to do with results that are mathematically checked
- Identity to complete
- Several mathematical representation to give
